8.33 kHz.
Several functions and settings are only available via the
password-protected "Configuration Settings*".
* For details please refer to manual:
http://www.becker-avionics.com/downloads/ →AR620X Family.

2.1.5. Safety-Conscious Utilization
Excessive pulses on the DC bus of the aircraft may cause
damage on electrical circuits of any installed instrument.
Do not switch ON the device during engine start or
shutdown.
A voice communication test shall be performed before
starting the engine.
It should be noted that, if the communication test is carried
out close to a ground station, the results may be positive
even if the antenna cable is broken or short-circuited. In
such a case, at a distance of 5 to 10 km and above,
communication might not be possible.
•Speak always loud, clear and not too fast for optimal voice
communication.
•Keep the microphone always close to the lips otherwise a special
suppressing circuit in the VHF COM will not be capable to suppress
normal cabin noise.
•Use only microphones or headsets which are suitable for use in an
aircraft.
oIn aircraft made of wood, synthetic materials or in gliders or
helicopters, incoming radiation can affect the integrated amplifier of
the microphone (feedback), noticeable in the ground station by
whistling and/or heavy distortion.
If the power supply voltage drops below the "Low Battery Threshold" (default value is
10.5 V), the "LOW BATTERY" message will appear each 3 seconds in the lower part
of the display.
If the power supply voltage drops below 10 V the system
enters power saving mode:
•Speaker output of the transceiver is automatically
switched "OFF"
•Speaker sign will no longer be presented on LCD display
•The pilot must use headphones to continue listening.
Channels store/change:
•The functions "LAST" and Store/Restore are only
available if they are activated in "Configuration Settings*"
- ("MEM OPTIONS").

is detected on the active frequency, receiving
signals on the preset frequency will be audible,
but will be muted as soon as a signal on the
active frequency is detected.
The device detects a:
"Long press": when pressing and holding down a key for at least 2 seconds (≥2s).
"Short press": any pressing below 2 seconds (< 2 s).
If any action by the user is invalid, the whole display inverting for a short time.

Excessive pulses on the DC bus of the aircraft may cause damage
on electrical circuits of any installed instrument.
Do not switch ON the device during engine start or shutdown.
•Turn "ON" the device by turning the volume knob clockwise.
oPower-On Built In Test is started.
•During PBIT (Power-On Built In Test) the display indicate the
messages:
o"WAIT".

oThe software version of "Core Module" (CM).
•If the PBIT has detected error(s),"FAILURE" appears on the display.
Details see "Warning and Failure Indications", page 32.
2.4. Receive and Transmit Mode
2.4.1. Receive Mode
If PTT (Push To Talk) inputs are inactive, the transceiver remains in receive mode.
In receive mode the headphone(s) outputs (if enabled) provide a mixed signal
consisting of:
•Received signal from antenna.
•Intercom signal from intercom circuit 1 and 2.
•Signal from auxiliary input.
In receive mode the speaker output (if enabled) provides a mixed signal
consisting of:
•Received signal from antenna.
•Signal from auxiliary input.
The signal from the auxiliary input been muted under certain conditions, for details
refer to "Auxiliary Audio Input (AUX)", page 25.
The signal from intercom can be attenuated or muted, under certain conditions, for
details refer to "Intercom Operation", page 26.
